Correct Question:
Two people push a car for 3s with a combined net force of 200N.
(a) Calculate the impulse provided to the car.
(b) If the car has a mass of 1200kg,what will be its change in velocity?
Answer-
(a) Impulse = impulsive force × time of impact
⟹ 200N×3s
⟹ 600N s
(b) Impulse = Change in momentum
= m×(v−u)
⟹1200kg×(v−0)=600Ns
⟹ v=
⟹ v=0.5ms^−1
